ALEXANDER S. JOHNSON, OF NEW YORK, N. Y., ASSIGNOR TO LOUIS G. LEYRER, CHESTER A. WELLER, AND EMMA L. JOHNSON, ALL OF SAME PL ACE..

ARTIFICIAL-STONE VESSEL.

SPECIFICATION forming part of Letters Patent No. 303,019, dated August 5, 1884.

Application filed January 19, 1884.

To all whom it may concern.-

Be it known that I, ALEXANDER S. J OHN- soN, of the city, county, and State of New York, have invented certain new and useful Improvements in Artificial-Stone Vessels, of which the following is a full, clear, and exact description.

My invention relates more particularly to artificial-stone wash-tubs, and it consists in pro- IO viding the tub with a metallic lining for protecting the bottom and side walls of the tub from being chipped off by hard substances, and for preventing the tub from being attacked by alkalies, 820., which corrode and destroy l 5 the solidity of the stone of which the vessel is composed.

The invention also consists in the method of making a water-tight joint between the lining and the walls of the vessel, the same consisting in molding the vessel upon its lining,

' or in molding the vessel with a groove upon the inside, into which the edges of the lining may be worked by a suitable tool, and cemented, if found necessary, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional elevation of an artificial-stone vessel having my invention applied thereto. Fig. 2 is a plan view of the same, and Fig. 8 is a sectional elevation showing the vessel formed with a groove to receive 3 5 the metallic lining.

A represents the body of the tub, which is molded of Portland cement or other artificialstone composition, and 13 represents the sheetcopper or other metallic lining of the tub.

In the form of tub shown in Fig. 1 the metallic lining B is formed with the flange, rim, or bead a, and is molded in the tub, or rather has the material composing the tub molded upon it by placing the metallic lining upon the core of the mold after the confining walls or sections of the mold are put in place. Then the artificial-stone material is properly packed in the mold and placed over the bottom of the metallic lining B in proper thickness and troweled off. After this the sections of the mold are removed, leaving the perfectly-formed vessel with the lining B solidly af- (No model.)

fixed to its inner surface and securely held in place by the narrow bead, flange, or rim a, forming a water-tight connection of the lining with the walls of the tub.

Instead of molding the lining 13 Within the tub A, the latter may have the groove 2) formed in its inner walls', as shown in Fig. 3, the groove being made at the point where it is desired to have the upper edge of the metal lic lining come. In this form of tub the metallic lining B will be placed in the tub after the tub is completed, and the upper edgeof the lining will be forced with a suitable appliance' or tool into the groove 1), and if found necessary, a hard-rubber or other water-proof cement will be placed in the bottom of the vessel, or in the groove 1), before the insertion of the linlng, so as to insure a perfectly watertlght and secure connection of the lining with the walls of the tub. In this manner it will vessels and not depart from the spirit of my invention,

Having thus described my invention, I claim as new and desire to secure by Letters Patent- .1. The artificial-stone vessel A, having the metallic lining B fitted therein, substantially as and for the purposes set forth."

2. The metallic lining B, formed with the bead a, and held in the artificial-stone vessel A by its bead embedded in the material of the "essel, substantially as and for the purposes set forth.

3. The artificialstone vessel A, having the groove]; formed in it for the attachment or fitting of a metallic lining therein, substantially as and for the purposes set forth.
